UNITED ,STATES AUGUST B. RIIPPE, OF SALT LAKE CITY, UTAH.

AWNING WINCH.

Application led March 2, 1925. Serial No. 12,657.

To all whom t may concern L' Be it known that I, AUGUST B. Rirrn, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Awning lVinches, of which the following is a specification.

lxly invention relates to awning Winches and has for its object to provide a new and economical means of raising and lowering awnings and of automatically locking the same to hold an awning at any desired position.

In the use of awnings in front of stores and windows it has been the practice to use a worm wheel drive or a number of sets of bevel gears for raising and lowering said awnings. With my device I do away with the use of the slow action of the worm gears and wheel and also use less bevel gears than has heretofore been the practice; I also provide means to automatically lock said device when the awning has been adjusted to the desired height.

These objects I accomplish with the device illustrated in the accompanying` drawings in which similar letters and numerals of reference indicate like parts throughout the several views and as described in thel specification and pointed out in the appended claims.

In the drawings in which I have shown the best and most substantial embodiment of tny invention, Figure 1 is a side elevation of my device in connection with a lowered awning. Figure 2 is an elevation showing the awning raised and locked, and with the winch turning member removed. Figure 3 is an end view of my device with the crank and unlocking key removed. Figure l is a front view of the end of my crank rod and unlocking handle and Figure 5 is a side elevation of the same.

In the drawings I have shown the common awning A with its supporting rods B attached to the wall of a building. A bevel gear 1v is secured on a horizontal'roller shaft C on which the body of the awning is wound. The teeth of said bevel gear 1 mesh with the tee-th of a bevel pinion 2, which is secured on a vertical shaft 8, which shaft is mounted in a bearing bracket that is firmly secured to the wall of the building. The said shaft C is journalled in bearings supported by the said'bracket 4c. The

lower end of the pinion shaft 3 is supported by a collar 5 thatlrests 4on another wall bracket 6. A catch 'is slotted and pivoted to and around the said pinion shaft 3, and which catch is weighted or made heavier at one end than the other end, in order that the heavy end of said catch will normally assume a position lower than the lighter end as shown in F igure 3. On the lighter end of said catch 7 a hook 8 is formed to engage said bracket 6 when the catch is in normal position. A U-shaped pin 9 is secured through the lower end portion of said pinion shaft 3 with the legs of said Us shaped pin bent upwardly and parallel with said shaft. A crank rod 10A is bifurcated at one end and each prong is bent to form a hook as shown at 11, and on the side of the rod opposed to the hook 11, a key plate 12 is attached.

The operation of my device is as follows: The prongs ll of the crank rod 10 are engaged over the `U-shaped'pin 9 which is the means for joining the crank rod 1() with the pinion shaft 3 and turning the pinion shaft 3. As the said hooks 11 are made to engage with the U-shaped pin 9 the key plate 12 will move the weighted end of they catch 7 upwardly to free the hook 8 from its engagement with the horizontal portion of the bracket 6. The said pinion shaft 3 may then be rotated in either direction by rotating the crank rod 10 to raise or lower the awning by rolling or unrolling the awning over the rod C. Vhen the said crank rod 10 is disengaged from the pinf ion shaft 3 the hook 8 of the weighted catch 7 will engage the horizontal portion of the bracket 6 and lock the awning in the position desired.

Having thus described my invention I desire to secure by Letters PatentV and claim:

1. An awning winch comprising, a set of.v bevel gears; bearing brackets for gsaid. gears; a pinion shaft having a U-shaped p1n y inone end thereof and said shaft secured to or connected with the pinion of saidl bevel gears; a pivoted locking member hav-.f .ing one end heavier than the opposite end;`

a bracket for supporting said pinion shaft, and a crank rod bifurcated and curved at one end for engaging said U-shaped pin with a key plate for moving said locking member.

,2- All ,awning winch comprising a bevel gear secured on one' end of an awning.y roller shaft; a bevel pinion whose teeth mesh with the teeth of said bevel gear; a verticalv shaft on which Said bev-ei pinion is secured; a bearing bracket in which the lower end of said pinion shaft is journalle'd; a U- shaped pin secured through the lower end portion of said pinion shaft with the legs of said pin extended upwardly; a weighted catohpivoted on saidlpinion shaft; a hook portion of said catch adaptedto normally hold the shaft against rotation; a-orank rod having one end hifuro'ated and bent to forni hooksto engage with the legs of sald Ylbshaped pin; and a key plate attached to the bifurcate'd end of said crank rod adapted to niove the heavy end portion of Said catch-'upwardly and disengage said catch roin its normal engagement with the pinion rod bracket.

In testimony whereof I have aHiXed in-y Signature.

AUGUST B. RIPPE.
